Check Digit Verification of cas no
The CAS Registry Mumber 151546-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,5,4 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 151546-28:
(8*1)+(7*5)+(6*1)+(5*5)+(4*4)+(3*6)+(2*2)+(1*8)=120
120 % 10 = 0
So 151546-28-0 is a valid CAS Registry Number.
